SIC-POVMs and Lie Algebras

ORAL

Abstract

A symmetric informationally complete positive operator valued measure (SIC-POVM) is usually thought of as a highly symmetric structure in quantum state space. However Appleby, Flammia and Fuchs (J. Math. Phys. \textbf{52}, 022202, 2011) have shown that the existence of a SIC-POVM in dimension $d$ is equivalent to a proposition concerning the Lie Algebra $\mathrm{gl}(d,C)$. Related to this they show that there is, associated to each SIC-POVM, a rich and intricate geometric structure in the adjoint representation space of $\mathrm{gl}(d,C)$. In this talk we present a deeper exploration of this structure.
